I have recently finished this application and is now fully functional. The application allows users to put together a greeting card where all items of the card are variables: backgrounds, messages and music.
The idea of GreetingCardBuilder.com was born out of realization that e-card sites do not allow enough customization on the cards and therefore the cards lose the personal touch or true meaning of the message they intend to convey.
Ingredients: Flash MX, ASP, XML and SQL. Check it out and let me know what you think.
